Streams Monitoring Home
The Stream and River Monitoring Program is part of the King County Department of Natural Resources and Parks, Water and Land Resources Division. We are committed to monitoring the water quality of the County's lakes and streams to ensure their continued health, as well as the health of the public who utilize the many freshwater resources.
